I love Linux but since KDE and Qt5 seem to spend most of their time broken to some extent I would not want to use it on my phone until it works, which given their history may be some time.
If KDe and Qt is broken most of the time, then I earn my complete income on a broken desktop environment. But I agree that Plasma Mobile is in early stages, but seems promising, at least to me. Ubuntu Touch is barely usable after a couple years of developement (I tested 2015 and 2016), so we should cut KDE some slack here :)
